Quantum erasure in the presence of a thermal bath: the effects of system-environment microscopic correlations
A. R. Bosco de Magalhães, J. G. Peixoto de Faria, R. Rossi
We investigate the role of the environment in a quantum erasure setup in the cavity quantum electrodynamics domain. Two slightly different schemes are analyzed. We show that the ef…
Toward irreversibility with a finite bath of oscillators
Artur Nogueira de São José, Patrícia Mascarenhas Dias, Arthur Rodrigo Bosco de Magalhães +1
We investigate the routes by which a bath composed of a finite number of oscillators at zero temperature approaches the induction of dissipation when it nears the usual limit of de…
Decoherence and Irreversibility: the role of the reservoir effective Hilbert space size
Adelcio C. Oliveira, A. R. Bosco de Magalhaes
We show that decoherence is determined by the effective Hilbert space size, and demonstrate that a few degrees of freedom system can simulate a "N" degrees of freedom environment i…
Classical and quantum coupled oscillators: symplectic structure
A. R. Bosco de Magalhães, C. H. d'Ávila Fonseca, M. C. Nemes
We consider a set of N linearly coupled harmonic oscillators and show that the diagonalization of this problem can be put in geometrical terms. The matrix techniques developed here…
Two cavity modes in a dissipative environment: cross decay rates and robust states
R. Rossi, A. R. Bosco de Magalhães, M. C. Nemes
We investigate the role of the cross decay rates in a system composed by two electromagnetic modes interacting with the same reservoir. Two feasible experiments sensitive to the ma…
Searching for Decoherence-Free Subspaces in Cavity Quantum Electrodynamics
A. R. Bosco de Magalhães, M. C. Nemes
We construct a model which describes a recently performed experiment (Phys. Rev. A 64, 050301(R) (2001)) in which an entangled state between two modes of a single cavity is built.…
